Secrets Config (TOML)

This document describes the TOML format for secrets.

Each secret has an alternative corresponding environment variable.

Also see the Node Config page.

Example

[Database]
URL = 'postgresql://user:pass@localhost:5432/dbname?sslmode=disable' # Required

Keystore = 'keystore_pass' # Required

Database

[Database]
